What is the meaning of thermos cup
May 22, 2022
The vacuum cup is generally a water container made of ceramic or stainless steel plus a vacuum layer. The top has a cover and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained inside to achieve the purpose of heat preservation.The thermos cup is developed from the thermos bottle. The principle of insulation is the same as that of the thermos bottle, but people make the bottle into a cup for convenience. There are many layers in the thermos cup. Its interlayer is generally vacuumed to prevent heat conduction, and then plated with silver, which can prevent heat radiation. Some cups have corks on top to prevent heat conduction.
